Hi, Sveta,
I am way behind in my email, since I haven't been online due to family illness. Thanks for your other email you sent me, btw. I have some info to write you on that, but it might be a week or so before I can get to it.
The only thing I do know about the 2 prong plugs is, even tho an appliance has a 2 prong plug, it still works best in one particular direction. So try the appliance plug both directions, and if you feel a difference, tape the top of the plug or paint it with a dot of nail polish, so you can easily distinguish it. Back when I was working on making my laptop more usable for me, a Dell tech told me to do this and that it would make a difference. It does.
I often plug 2 prong plugs into a grounded power block (same as a power strip except it is square and uses both sockets of an outlet). The only problem with this is sometimes power strips or blocks cause their own bad frequencies, so you might have to buy and return some before you find one which works without causing you symptoms. I especially like to do this with tvs/ vcrs/ other electronics.

Noone has any bits of knowledge, speculation, etc. to share on this?
Thanks,

Even some relatively-large, major electronics - like TVs, and VCR-DVD combo players - are manufactured with 2-pronged cords. Why are so many electronics manufacturers opting for the 2-pronged power cords over 3-pronged cords? Is it simply a matter of cost-cutting?

Back in the "good old days" - I would have 2 VCRs in my room at the same time (and one of those VCRs was a dual-deck one) with no obvious problems - so I didn't really anticipate that this VCR-DVD player would give me symptoms. And I noticed, despite it being a relatively-large device (by today's standards) that I guess uses a fair amount of power - it has a 2-pronged power cord. I'm wondering if figuring out some way to "ground" this device would make a difference.
